MT8852A Option 15 Adaptive Frequency Hopping Option (AFH) What is Adaptive Frequency Hopping?
When two Bluetooth devices connect under normal circumstances, they establish a basic frequency hopping scheme across 79 frequency channels in the 2.4 GHz ISM band, hopping at a rate of 1600 times per second. However, as is becoming increasingly common, interference may be encountered in environments where other wireless technologies, such as 802.11 WLAN or DECT are also active. Blocked channels, caused by interference, result in a deterioration in the performance of the connection, and this in turn results in poor voice quality or reduced data transfer rates. To limit the impact of this interference, an adaptation of frequency hopping, known as Adaptive Frequency Hoping (AFH) was introduced by the Bluetooth Special Interest Group in the 1.2 Bluetooth s……
